Re: Team 869's Custom Controller

Rohit,
I know that this will not be a problem during competition since you will be using an IFI radio for the OI but the radios actually have an internal antenna that runs down the left side of the modem in your picture. Mounting this against a metal panel usually has a detrimiental affect on RF. the same goes for the RC side as well.

What he means is that you have your OI radio modem mounted to what appears to be a metal plate. This metal plate is in between the OI modem and the robot, and will interfere with the communication. What he's suggesting is that you mount the modem so that it's above the metal or otherwise unattached to it. The silver antenna on the outside of the modem isn't the only one - there's also one inside the black case which is why just having the external antenna above the metal plate isn't good enough.

That is nothing. I will see if i can post a picture of my team's OI. It is built from ITEM and Lexan and weights from ten to twenty pounds. The drivers only saw ours for a brief period of time and started complaining lol. I just hope they don't drop it when they actually have to pick it up on game day.

Re: Team 869's Custom Controller

Our contols were at one time too large to use on the field corectly, since there was not long enough cable between the zip ties and out competition port on the fields. We ended up haveing to remove 6" off each side to make it work. The box was so large it required a hing to make it easier to carry and wheels since it was 25 lbs. It was made out of item, and lexan with our joysticks top mounted, I will try to get a picture on her soon.
